The LCM of 583,138,390,870 is 151655790.
Find LCM of 583,138,390,870 with Prime Factorization
| 2 | 583, 138, 390, 870 |
| 3 | 583, 69, 195, 435 |
| 5 | 583, 23, 65, 145 |
| 583, 23, 13, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 583 x 23 x 13 x 29 = 151655790
Therefore, the lowest common multiple of 583,138,390,870 is 151655790.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
583 x 138 x 390 x 870 = 27298042200
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
583 : 1, 11, 53, 583
138 : 1, 2, 3, 6, 23, 46, 69, 138
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 583,138,390,870, is 1.
Now, the common factors can be found like this.
583:11x 53
138:2x 3x 23
390:2x 3x 5x 13
870:2x 3x 5x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3x 3x 5 = 180
Therefore, the value for common factors is 180.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 27298042200/(1x180)
LCM = 27298042200/180
LCM = 151655790
Thus, we can understand that the LCM of 583,138,390,870 is 151655790.
